Get the facts

Your options

Get allergy shots to make you less sensitive
to insect stings and reduce the risk of a severe allergic reaction (anaphylaxis).

Do not get allergy shots, and try other things such as avoiding
stinging insects and carrying epinephrine to deal with the risk of a severe allergic
reaction.

Key points to remember

If you have been
stung in the past and had an allergic reaction to the sting, you have a high risk
of having a similar reaction if you are stung again.

Allergy shots usually are recommended only for people who have
already had an anaphylactic (life threatening) reaction to an insect sting.

If you had an
anaphylactic reaction in the past,
allergy shots greatly reduce your risk of having another.footnote 1

Whether you need allergy shots depends on your reaction to an insect sting in the past. You may not need allergy shots if you had a normal (localized) reaction, a larger local reaction, or one that caused swelling and redness to much of your body but did not cause anaphylaxis.

If you have had
allergy tests that found one or more sensitivities to
insect stings, allergy shots can prevent life-threatening reactions and also
make you less worried about insect stings.

Allergy shots may not be
safe for you if you have an
autoimmune disease or take certain kinds of medicines (such as beta-blockers or ACE inhibitors).

Allergy shots can hurt a little, may trigger anaphylaxis in
some people, can be costly, and usually take 3 to 5 years to complete.

Minor allergic reactions occur around the site of the sting. This is
called a localized reaction, and it can cause pain, itching, redness,
swelling, and hives near the site of the sting.

Large local reactions may cause the same symptoms as mild reactions, plus redness and swelling that affects large parts of your body, such as an entire arm or leg.

Systemic reactions are those that spread throughout your body. One type may only involve your skin, causing hives or deeper skin swelling (a cutaneous reaction), but it does not affect the tongue or throat or cause breathing problems. A more serious type of systemic reaction can cause symptoms such as swelling of the tongue, throat, or other body parts.

A life-threatening systemic allergic reaction called
anaphylaxis can cause severe symptoms such as confusion,
trouble breathing,
shock, and sometimes death.

Allergy shots work by
putting small amounts of insect venom into your body, making you less sensitive
over time to the venom.

Getting a series of allergy shots can
prevent a systemic allergic reaction or make it less severe. Allergy shots aren't needed if you have a mild reaction, a large local reaction, or even a systemic reaction that only affects your skin. Only
about 4 to 10 people out of 100 who have these kinds of reactions to insect stings go on
to have a more serious, anaphylactic reaction.footnote 1
This means that 90 to 96 out of 100 people who have localized reactions don't ever have an anaphylactic
reaction to an insect sting.footnote 1

Allergy shots can greatly reduce your risk of having
another life-threatening reaction if you've had one before. Imagine a group of
100 people who have had a life-threatening reaction. Without allergy shots, up to 60
of those 100 people will have another life-threatening reaction in the future.
But if those 100 people get allergy shots, only 5 of them will have another
life-threatening reaction.footnote 1 This treatment is most effective after an entire course of allergy shots is complete.

After allergy
tests have identified the insect(s) you are allergic to, you can begin to get
the shots. At first, you will get weekly shots of small doses of venom and
allergens from the insect(s) that cause your allergies. After about 4 to 6
months of weekly shots, you will get a regular dose, called a maintenance dose,
every 4 weeks for another 4 to 6 months. Finally, you will keep getting monthly
shots for 3 to 5 years, depending on the type of stings that cause your
allergies. For example, fire ant allergies require longer treatment than other
stinging insect allergies.

If
you have had severe reactions to insect stings in the past, you may want to get a series of allergy
shots on a faster schedule. For this you get allergy shots every few hours on one day or every few days. This helps to rapidly
increase your tolerance to an allergen. After the first shot, you must wait to
see if you have a reaction to the shot. If you don't have a reaction, you get
more shots throughout the day. You (or your child) may feel anxious about
receiving the next shot. So it may help to bring a book or something to
distract you while you wait.

This treatment usually works in 1 to
8 days instead of the standard treatment, which takes several months. You may
have this "rush" treatment if you have severe or life-threatening allergic
reactions to insect stings, are a long distance from any type of health care
center, have severe
allergic asthma, or are about to travel.

Allergy shots
are safe for most people. The most common side effects are redness and warmth
at the injection site. Some people may have large local reactions that include
itching, hives, or swelling of the skin near the injection site.

But allergy shots can trigger a more serious reaction, which
may include trouble breathing or swelling in the deep layers of the skin. In
rare cases, a person may have a life-threatening allergic reaction (anaphylaxis) to the shots. Because of this, the shots
are given in a clinic or other health care setting where emergency care can be
provided if needed.

Talk with your doctor if you have an
autoimmune disease (such as
lupus) or are taking medicine for heart problems (such
as
beta-blockers). Allergy shots may not be safe for
you.

You are younger than 16 and
had a mild skin reaction all over your body (cutaneous reaction) without any
other symptoms.

You tried allergy shots before, but the shots
triggered a moderate to severe allergic reaction.

Personal stories about allergy shots for insect stings

These stories are based on information gathered from health professionals and consumers. They may be helpful as you make important health decisions.

I have had
systemic reactions to insect stings before, although none were
life-threatening. I work in the landscaping and grounds maintenance industry,
so I am outdoors almost every day mowing lawns, trimming hedges, tending
flowerbeds, and similar activities that really put me at risk of getting stung.
I carry an epinephrine shot to my work sites, but I wanted to do something to reduce
my sensitivity to stings and cut the risk that I might have a really bad
reaction. So I've decided to have immunotherapy.

Rudy, age 26

I have what
must be a mild allergy to bee stings. I've been stung three or four times over
the past decade, and I always swell up quite a bit-my whole arm or leg or
wherever the sting is-and break out in hives around the sting, too. But it
never gets any worse than that. For me, allergy shots would just be too much
bother and expense for something that only happens once in a great while, and
my doctor tells me it's not really needed. My doctor and I make sure I have
an up-to-date epinephrine shot just in case, but I've never had to use it.

Max, age
57

Our daughter was 14 years old when she had
a pretty severe reaction to a yellow-jacket sting. She had swelling over most
of her body and a bad outbreak of hives. She was very frightened. After talking
it over with our doctor and an allergist, we decided to have her take allergy
shots. They told us her risk of having another similar reaction was fairly
high, and we felt it was worth the cost and the bother of having the allergy
shots to reduce the risk. We also make sure she keeps her epinephrine shot close by.

Maureen, age
37

Our 7-year-old boy was stung on the
shoulder by a hornet at a family picnic. He was uncomfortable with a patch of
hives across his back, but he got over it without anything worse. After talking
things over with our pediatrician, we decided allergy shots wouldn't be needed.
The chances he'll have another reaction like that are pretty low. But we do
keep an epinephrine shot at home and with the nurse at school.

FAQs

What are allergies to insect stings?

An
allergic reaction to a sting occurs when your body's
immune system overreacts to substances called
allergens in the venom of stinging insects such as
bees, wasps, hornets, or fire ants.

What are the different types of allergic reactions?

Minor allergic reactions occur around the site of the sting. This is
called a localized reaction, and it can cause pain, itching, redness,
swelling, and hives near the site of the sting.

Large local reactions may cause the same symptoms as mild reactions, plus redness and swelling that affects large parts of your body, such as an entire arm or leg.

Systemic reactions are those that spread throughout your body. One type may only involve your skin, causing hives or deeper skin swelling (a cutaneous reaction), but it does not affect the tongue or throat or cause breathing problems. A more serious type of systemic reaction can cause symptoms such as swelling of the tongue, throat, or other body parts.

A life-threatening systemic allergic reaction called
anaphylaxis can cause severe symptoms such as confusion,
trouble breathing,
shock, and sometimes death.
